sql - ORA-04071 : missing BEFORE, AFTER 或 INSTEAD OF 关键字错误

Question

CREATE TRIGGER TRG_LOADMONEY
ON KIOSK
AFTER INSERT
AS
DECLARE @LOADEDCARDID INT
DECLARE @LOADEDAMOUNT INT

SELECT @LOADEDCARDID = LOADEDCARDID, @LOADEDAMOUNT = LOADEDAMOUNT FROM INSERTED
UPGRADE CARD SET CHARGE = CHARGE + @LOADEDAMOUNT
WHERE CARDID = @LOADEDCARDID

我运行此代码，但出现错误“ORA-04071:缺少 BEFORE、AFTER 或 INSTEAD OF 关键字”。我有 AFTER 语句，我不明白问题出在哪里。

Answer 1

您使用的语法是针对 sql server 的。

试试这个:

CREATE OR REPLACE TRIGGER TRG_LOADMONEY
AFTER INSERT
ON KIOSK FOR EACH ROW
/*  
 These variables are not required because Oracle triggers can reference the table's
 columns directly using the :OLD and :NEW prefixes.   
 DECLARE 
     LOADEDCARDID PLS_INTEGER;
     LOADEDAMOUNT PLS_INTEGER;
*/
BEGIN
   UPDATE CARD 
      SET CHARGE = CHARGE + :NEW.LOADEDAMOUNT
    WHERE CARDID = :NEW.LOADEDCARDID;
END;
